喇嘛甸油田水驱进入特高含水期后,剩余油分布零散,综合含水高,层间、层内矛盾突出,稳产难度不断加大。注水状况的好坏,直接影响着油田开发效果。本文紧紧围绕“注好水、注够水、有效注水”的注水结构精细调整原则,以“控制无效循环、增加有效注入”为精细调整的重点,在保持注采平衡的前提下,通过细分注水、周期注水、平欠层治理等手段,优化注水结构调整,夯实油田稳产基础。 Lamadian Oilfield water flooding into the ultra-high water cut period, the residual oil scattered, high water content, layers, layers within the contradictions, steadily increasing the difficulty of increasing. Water quality is good or bad, a direct impact on the development of the oil field effect. In this paper, we focus on the principle of fine adjustment of waterflooding structure of “good water, enough water, effective waterflooding”, focus on fine adjustment with “control invalid cycle and increase effective injection ”, By means of subdivision water injection, periodic water injection and leveling management, the structure of water flooding is optimized to consolidate the stable foundation of oilfield.
